| (Selection Background Color Error) |
| |
| This bug is caused when the selection background is inverted if it |
| is the same as the text color. However, it should compare against |
| the selected text color instead of the non-selected text color. |
| |
| The alpha component must be non-opaque for the bug to get triggered. |
| This is because when the selection background is opaque, it will be |
| blended with white, which prevents the inversion. |
